ICE-ELEVATOR CHAIN.

SPECIFICATION forming part of Letters PatentNo. 545,690, dated September3, 1895.

Application filed April 10, 1895. Serial No. 545,157- (No modeLl T0 (ZZZwhom it may concern: I

Be it known that I, LEMONT HUNTER, a citi zen of the United States,residing in Chicago, in the county of Cook and State of Illinois,

have invented a new and useful Improve-v ment in Ice-Elevator Chains, ofwhich the following is a specification.

This invention relates to an improvement in the construction ofice-elevator chains, and more particularly to the construction andmethod of attachment of the cross-bars of such chains. These cross-barshave ordinarily been made of a solid wooden bar rectangular incross-section and having a tenon at each end, fitting into a casting, towhich it is pinned or bolted, and the casting. in turn secured to thechain. Such bars: frequently break, split, or become detached,with\their castings are heavy, and, moreover, gather snow or ice chipsor water, which freezes upon them, rendering the chain heavy to operateand causing stoppages for repairs, when a large force of men are-thuscaused'to be idle during the mending. I have found that all'of thesedefects may be overcome in an exceedingly efiicient and simple manner byconstructing the cross-bar and its end attachments all in a single pieceof angle iron orsteel, the end attachments being formed by slitting theiron at the angle and bending the two parts. at right angles to eachother in two unequal pieces, which are punched with holes to receivebolts or rivets from the chain; and my invention consists in this newstructure, as will be better understood from the following descriptionand claims.

In the accompanying drawings, which form a part of this specification,Figure 1 is a sectional side elevation of a portion of an iceelevator,showing the invention. Fig. 2 is a plan view; and Figs. 3, 4, 5, and 6are perspective views, upon a larger scale, illustrating theconstruction of the improved bar and its method of attachment to thechain.

Like letters of reference made use of in the several figures denote likeparts wherever used.

In said drawings, A is a fragment of the ordinary elevator-way.

B B are the elevator-chains, one at each side of the way.

C is the improved bar, made of angle iron or steel. Each end of this baris cut into two parts by a slit along the corner or angle. One of theseparts 0 is shown equal in length to the width ofa side of the bar. Theother 0 is shown equal in length to the length of one of the links ofthe chain. Through the part c is'pierced a hole at and through the part0 two holes d (P. The parts 0 0' are bent at right angles, as indicatedmore clearly in Figs. 3, 4, 5, and 6, to form a means of attachment ofthe bar to the chain and to strengthen the bar. The holes d (1' (Z? maybe pierced either before or after the bending of the parts 0 0',according to the convenience of the work.

To attach the bars to the chain, the two riv ets of a link are removedand bolts or longer rivetse e, long enough ,to pass through the link andthrough the holes (I d, &c., substituted. This forms a firm, attachmentattwo points for thebar at each end to the two chains, so that the barcannot turn or roll over. I

In attaching the bar to the chains, one of the flanges of the angle-ironis placed to the front to come in contact with the ice, and the otherflange extends from the upperiside, so that the cavity or hollow of theangle-iron will not catch or retain fragments of ice and so that thegreatest strength of the bar may be utilized in moving the iceblocks tobe elevated.

I claim- .1. The crossbar for ice elevators, consisting of an angle iron'bar having its ends slit, bent at right angles and pierced forattachment to the elevator chain, one of said parts being the short partand the other a long part, substantially as specified.

, 2. The ice elevator, consisting of a suitable frame work, two chains,and a series of angle iron cross bars having both ends slit and bentinto parts of unequal lengths and attached at each end at two pointsto-a link of the chain at the connection between said link and theadjacent link, substantially as specified.
